Engineered Nanostructured Nitrogen-Doped Carbon Network (Ndc) Electrodes With Unprecedented Cycling Stability For Water Capacitive Deionization In Harsh Conditions, Soha Essam Anwar
Theses and Dissertations
Capacitive deionization (CDI) is a feasible low-cost desalination technique for low-to-medium (brackish) salinity water. However, cycling stability and regeneration of the CDI electrodes are the bottlenecks hindering the practical application of the technology on large scale. Oxidation of the electrodes during the sequential adsorption-desorption processes is one of the most challenging problems hindering their long-term cycling performance. Herein, we demonstrated the ability to design and fabricate exceptionally stable CDI electrodes via a one-pot pyrolysis protocol. The optimized pyrolysis of nitrogen-carbon precursors at different temperatures enabled the fabrication of carbon materials with a controlled amount nitrogen dopant (NDCs) with exceptional cycling …

Can The Circular Economy Concretize Sustainability? A Construal Level Approach To Encourage Sustainable Consumption., Jolie Gutentag
Theses and Dissertations
Despite a growing awareness and understanding of the impact our lifestyles have on the environment, most people have not adequately changed their consumption patterns. One possibility for the disconnect is the perceived abstractness of sustainability. Drawing on construal level theory, this research proposes that framing environmental sustainability as circularity, using the principles of the circular economy, reduces the perceived abstractness of sustainability. Four studies investigate the effects of circular framing on sustainable consumption behavior, including the moderating role of consumers’ chronic level of construal, an innate mindset reflecting a tendency to view information more concretely or abstractly. Findings provide initial …
